run Rev app on two networked computers?

Rosli,

This is a good idea and should work with the following caveats...

1) I'd wrap the write statement with a try/catch handler, because if 
both apps try and write at the same time, it will throw an error as the 
file is locked when opened in an append for write mode (or so I would think)

2) The file would need to reside on a shared volume of some sort. You 
could also probably do the same with FTP, though I belive the 'lock' 
periods would be longer.

In fact, I always prefer storing my data 'agnostically' in text or 
binary format rather than stack files...

best,

Chipp
